The Moon and Venus will share the same right ascension, with the Moon passing 4°03' to the south of Venus. The Moon will be 3 days old.

At around the same time, the two objects will also make a close approach, technically called an appulse.

From Ashburn (click to change), the pair will become visible at around 17:45 (EST) as the dusk sky fades, 38° above your south-western horizon. They will then sink towards the horizon, setting 3 hours and 50 minutes after the Sun at 21:16.

The Moon will be at mag -10.6 in the constellation Aquarius, and Venus at mag -4.6 in the neighbouring constellation of Pisces.

The pair will be too widely separated to fit within the field of view of a telescope, but will be visible to the naked eye or through a pair of binoculars.

A graph of the angular separation between the Moon and Venus around the time of closest approach is available here.

The positions of the two objects at the moment of conjunction will be as follows:

Object Right Ascension Declination Constellation Magnitude Angular Size
The Moon 23h47m10s -03°34' Aquarius -10.6 31'36"2
Venus 23h47m10s +00°29' Pisces -4.6 30"6

The coordinates above are given in J2000.0. The pair will be at an angular separation of 44° from the Sun, which is in Capricornus at this time of year.

The circumstances of this event were computed using the DE405 planetary ephemeris published by the Jet Propulsion Laboratory (JPL).

This event was automatically generated by searching the ephemeris for planetary alignments which are of interest to amateur astronomers, and the text above was generated based on an estimate of your location.
